In the past bitcoiners could purchase a machine called the “Ghost Gunner 2,” from a Texas company called Defense Distributed (DD) led by crypto-anarchist Cody Wilson. A Ghost Gun is a firearm that is built or modified without serial numbers and the company’s product makes untraceable AR-15 rifle parts. Now, this week Wilson has announced the Ghost Gunner 2 has implemented new software that can mill an aluminum frame of an M1911 handgun.
